UNITED STATES PATENT OFFICE FRANK I. BLACK, 0F KINGS MILLS, OHIO;

STRAINER FOR WATER-FIRES.

Specification of Letters Patent. Patented J 1y 28, 1914, Applicationfiled. April 26, 1913. Serial No. 763,879. a

To all whom it may concern:

Be it known that I, FRANK L. BLACK,

This invention relates to strainers for water pipes and moreparticularly to that class which is adapted to prevent the accumulationof debris thereon, an object of the invention being the provision ofregistering strainers which are arranged on the interior of a casing,the strainers comprising transverse bars arranged at an inclinationtherein so that the leaves etc, will be automatically carried through anexit in the front of the casing, thereby preventing the clogging of thesame as has hertofore been the case in the use of wire meshingetce orwhen the strainers were arranged'horizontally within a casing.

Other objects as well as the nature, characteristic features and scopeof my invention will be more readily understood from the followingdescription taken in connection with the accompanying drawings andpointed out in the claims forming a part of thisspecification whereinFigure 1 is a perspective view of my improved device showing the exitopenings in the front of the casing and the arrangement of the strainerstherein; Fig. 2 is a vertical sectional view taken on the line 22 ofFig.

1 showing the manner in which the strainers are secured in the casing;and Fig. 3 is a cross sectional view taken on the line 8-3 of Fig. 1. I

In the drawings wherein is shown the preferred form of my invention thenumeral 5 indicates an inlet pipe which may be from the roof of a houseor any other place from which water is drained and is secured to the cap6. A casing 7 is providedwhich is formed of a single piece of metal andis provided with a double rear wall by the folding over of the oppositeends 8 and 9 respectively thereof. Exit openings 10 and 11 are formed inthe front face of the casing 7 and have flanges 12 bent inwardly at anobtuse angle to the face thereof which are adapted for the reception ofthe one end of wall and the outer wall 9. The walls 8 and 9 are'held inclose proximity to each other through the medium of the cap 6, on the upper end of the casing and a cap 15 on the lower end of the casing, thesaid cap 15 having an outlet pipe 16 extended therethrough the same asthe pipe 5' through the cap 6. Said bars 13 and 14 comprise the upperand lower strainers respectively.

The strainer 13 which comprises a plurality of bars arranged parallellyin the casing in spaced relation to each other and being inclined sothat the debris or foreign through the innermost of the rear walls 8 vand bent downwardlybetween said inner matter which comes through thepipe 5' will be caught thereon and carried through the opening 10 in thefront of the casing. The strainer 14: is identical inevery respect withthe strainer 13. except that the barsv of the former are arranged inclose proximity to each other so that the smaller particles which passthrough the bars 13 which comprise the upper strainer will be caught andcarried through the exit 11 in the lower end of the casing. I

The greatest stress is to be laid on the fact that the casing is made ofa single piece l of metal having a double rear wall so that, the one endof the bars may be securely held therebetween and the opposite endsecured to the inwardly extending flange 12, the said bars to beinclined so that the accumulation of debris will be reduced to aminimum.

Another feature which this invention contemplates is the arranging ofthe parallel bars so that the finer particles may be caught I andautomatically carried therefrom, which has been found to be impossiblewith wire meshing and many other expedients which have been "used forthis purpose, as leaves etc., have a tendency tobe caught inthe smallrectangles of wire mesh thereby clogging the strainer and preventing thefree passage of water therethrough.

It will be understood that the above description and accompanyingdrawings comprehend only the general and preferred em bodiment of myinvention and that various minor changes in details of construction,proportion and arrangement of the parts may be made within the scope ofthe appended claims and without sacrificing anv of the advantages of myinvention.

Having thus fully described my invention What I claim as newand desireto Se.- cure by Letters Patent is i A device of the character describedincluding a casing, said casing comprising a sheet of metal, theopposite ends of which. are overlapped to provide a double rear wall,strainers arranged in said casing, one end of each of which is securedto the front wall of said casing, and the opposite end there- 10 ofengaged between the rear Walls, caps arranged on the. onposite ends ofsaid casing for holdlng sald rear Walls 1n engagement with sa dstrainers, and adapted for en" H.
